Not a 100% sure, but I think this is due to the QMaemo5 style implementation
you are not able to do it.
Think Ive faced the issue before.
Is there a chance you could try with a delegate for your columns, thats worked
for me.
Implementing the paint().
P.S. i dont use python, I use C++, hence I didnt paste the example.
cheers,
Ram

Subject: PyQt ForegroundRole
Hello, I've been struggling getting ForegroundRole
http://doc.trolltech.com/4.6/qt.html to work properly so I can change the text
color of certain cells in QTableView.
I took an example from http://www.daniweb.com/forums/thread191210-7.html
http://www.daniweb.com/forums/thread191210-7.html and added the following in
the data(...) method:
elif role == Qt.ForegroundRole:
return QBrush(QColor(255, 0, 0))
When I run it on my Windows PC, the font color is set to red for all the cells
but does not seem to have an effect on my N900.
Is there any Maemo-specific calls that I am missing here?
